DEVICE FOR THE PREVENTION OF OIL DRIP IN SOCK-RIBBING MACHINES.

Application filed May 3,

To all whom it may concern:

Be it known that we, WILLIAM H. CoBBLE and HORACE W. COBBLE, citizens of the United States, and residents of the city of Chattanooga, county of Hamilton, State of Tennessee, have invented an Improvement in Devices for the Prevention of Oil Drip in SOck-Ribbing Machines, of which the following is a specification.

Our invention relates to the hosiery manufacturing industry and more particularly to the prevention of the ill effects brought about by the oil drip which is common in the ribbing process of the industry, and which is injurious to the finished product.

Heretofore in the ribbing process a great drawback has been that oil running through the oil groove on the shaft on which the dial is mounted tends to drip onto the fab ric and produce a discoloration therein which the coloring dye cannot overcome. The fabric so discolored is therefore useless for the manufacture of anything but a black stocking, and material of the value of several thousand dollars is wasted in a year by being thus discolored with this dripping oil.

By the device which is the subject of our invention, we provide a means of effectually preventing this undesirable flow of oil. We provide a receiver which may be suitably attached to the oil egress nozzle and which is easily removable from time to time to discharge the oil which has collected therein.

The preferred embodiment of our invention can be best illustrated with reference to the accompanying drawings in which Figure 1 is a side elevation of the dial portion of a ribbing machine with our device attached.

Figure 2 is a section on the line 22 of Figure 1.

Figure 3 is a cross section on the line 33 of Figure 2.

Similar reference characters refer to similar parts in the different views illustrated.

In the drawings 1 denotes the dial of an ordinary ribbing machine, mounted on the dial shaft 2, on the surface of which runs a groove 3 for collecting and carrying away the excess oil from the apparatus, the groove being tapered at either end as at 4, 4: To the lower end of this dial shaft our device may be attached in any suitable manner as by a set screw 5. The device is preferably connect with the drain 11.

made in'two parts, in order that the set screw need not be removed every time the receptacle is emptied. The receptacle proper is denoted by 6, and the top portion 7, adapted tobe attached to the dial shaft 2, is preferably screw threaded to fit therein. The dial-shaft 2 projects into the top portion 7 for a considerable distance so that the oil may drip directly into the container 6, and there will not. be much tendency for it to spatter outside. Some spattering-of the 'oil will occur,however. To effectually prevent this the attaching portion 7 is flanged at the top, as at 8. A beveled boss 9 about the center of the attaching portion in conjunction with the flanged portion 8 provides a groove 10 in which any oil which may spatter is trapped and caused to pass down through drain 11 into the receptacle 6. To aid in the discharge'of any trapped oil in the top of the attaching portion the inner wall thereof is notched as at 12 to Any overflow may leave the top portion 7 by way of either exits 11 or 12.

When the receiving portion is full of oil it is easily unscrewed, the oil thrown away and the receptacle rep-laced as before.

It is understood that we do not limit ourselves to the specific embodiment discussed herein, which is merely for the sake of illustration as it is obvious that many changes in details of the construction may be made within the scope of the appended claims.

We claim as our invention:

1. Oil drip attachment for sock-ribbing machines comprising an attaching portion flanged at its upper or attaching end, and a receptacle portion removably attached to said attaching portion.

2. Device of the class described comprising an attaching member, a receptacle member and means in the attaching'inember for catching and holding any liquid which may spatter.

3. Device of the class described comprising an attaching member, a receptacle member, means in said attaching member for catching and holding any splash and means.

for removing said splash from. said retaining means.

4:. Device of the class described compris ing an attaching member, a receptacle mem ber, means in said attaching member for catching and holding splash, an oil duct leading from said retaining means to said receptacle member and a supplementary duct in the Wall of the attaching member at a point below said retaining means.

5. A device of the class described comprising an upper or attaching -portion flanged at its upper or receiving end and provided With a hollow center adapted to receive the end of the dial shaft, and a raised circular boss around said hollow receiving center, said boss being so constructed as to leave a groove around the inner edge of said attaching member, and a drain hole in the edge of said boss to permit of the escape of the oil into a receptacle member removably attached to said attaching member.

6. A device of the class described comprising an attaching member, a receptacle member, means for attaching said attaching member to the dial shaft of a ribbing machine, an oil groove in the top of said attaching member, a drain through said attaching member, said attaching member being provided With a notch on the inner Wall thereof and connecting With said drain to assist in discharging the overflow of oil through said drain.

'4'. Device of the class described comprising an attaching member, a receptacle member, means comprising a flanged groove in said attaching member for catching and retaining spray or splash, anoil duct leading from said retaining means, and a sec- 0nd oil duct opening from the inner Wall of the attaching member and connecting With the first-mentioned duct substantially as described. 7

In testimony whereof, We have signed our names to this specification this 24th day of April 1923.
